The working mechanism of the flexible reinforcement of the cut slope in expansive soil was explored to promote the new technology.Ģ Basic properties of expansive soil in Nanning outer ring
The stress, strain of soil, and slope stability of the treated slope were compared with those of bare excavated slope. Moreover, their interaction in the cut slope in expansive soil treated with a geogrid flexible reinforcement structure was evaluated. Therefore, numerical simulation was performed to analyze the stress and deformation of the geogrid and soil on the actual construction and change in environment at the cut slope in the expansive soil along the Nanning outer ring expressway. However, the wide application of this technology is limited by the lack of publicity and promotion, and studies on its working mechanism and design theory. The technology of flexible reinforcement of cut slope in expansive soil has been listed in 2011 as one of the promoted scientific and technological achievements in transportation construction. A vast area of vegetation along the slope has become a beautiful scenery of the Nanning to Youyiguan expressway. Fourteen slippery but stable slopes treated by this technology were subjected to the effects of atmospheric wet and dry cycles for eight years and several typhoon rainstorms.
Reinforcement technology using flexible geogrids was first applied to treat the cut slope in the expansive soil in the Ningming section of the constructed Nanning to Youyi-guan expressway. The heavy disaster area of expansive soil engineering was selected in this project. Changsha University of Science and Technology organized a project named "Complete Technology of Road Construction in Expansive Soil Area", which was sponsored by the Ministry of Transportation of the People's Republic of China in 2002, to eliminate or mitigate geological disasters. Swelling and softening during moisture absorption, as well as shrinkage and cracking during loss of moisture, result in serious damage to the infrastructure. #0 Foam::error::printStack(Foam::Ostream&) at ?:? #1 Foam::error::abort() at ?:? #2 Foam::heRhoThermo >, Foam::sensibleEnthalpy>::calculate() at ?:? #3 Foam::heRhoThermo >, Foam::sensibleEnthalpy>::correct() at ?:? #4 ? at ?:? #5 _libc_start_main in "/lib/x86_64-linux-gnu/libc.so.In practical engineering, changes in the volume of expansive rock or soil with varying water content lead to frequently repeated deformations. > FOAM FATAL ERROR: Maximum number of iterations exceededįrom function Foam::scalar Foam::species::thermo::T(Foam::scalar, Foam::scalar, Foam::scalar, Foam::scalar (Foam::species::thermo::*)(Foam::scalar, Foam::scalar) const, Foam::scalar (Foam::species::thermo::*)(Foam::scalar, Foam::scalar) const, Foam::scalar (Foam::species::thermo::*)(Foam::scalar) const) const in file /home/ubuntu/OpenFOAM/OpenFOAM-4.1/src/thermophysicalModels/specie/lnInclude/thermoI.H at line 66. I have some problem with chtMultiRegionSimpleFoam As an example application, one of the current areas of interest in where CODE_BRIGHT leads is the nuclear waste disposal management and repositories design with topics including gas propagation through clay materials, internal cracking evolution, material heterogeneities, etc. The use of high-quality numerical modelling research through CODE_BRIGHT is confirmed/justified with many journal paper publications you can find in the bibliography as reference (). Indeed, despite maybe not as user-friendly as other FEM softwares, CODE_BRIGHT () allows to go deeper in the numerical modelling philosophy with an accurate meshing process in 2D and 3D (in terms of mesh discretization and type of finite elements to use) through the pre&post processor GiD (), construction stages, as well as plenty of constitutive models availbale (some of them quite special/unique, as partially saturated soils case studies) for THM purposes.
